| Abstract: | An experiment was conducted to study the wind-resistant control based on Matlab/Simulink software platform using Daqing TV tower as testing materal. Twenty-one pieces of time-history of turbulent wind were simulated by the model of wavelet analysis. The effect of the semi active control based on LQR algorithm was analysed under wind load using magneto-rheological damper as semi active control device. Results show that the application of magneto-rheological damper to vibration control system can effectively reduce the responses of Daqing TV tower. Simulink simulation technique with the advantages of friendly interface and highly visual characteristics has a very good development prospect in wind-resistant control. |
